I found possibility change SCP format to HEX but it only copies HEX to clipboard

Also need to show HEX code beside a cursor where RGB right now

I don't see point of seeing hex there.
It is very useful when there is a need to compare known hex color with existing, for example, after image compression some colors can be distorted. And I just hover SCP on it to check, without copying to clipboard.
Now I need to use PicPick for this purpose
Thank you! Was wondering where I could change this.
You mean this?

Yes. It does support $hex. Which is perfect. I use that feature fairly regularly. Much easier than screenshotting and pasting into PhotoShop like I used to do.
the screenshot above is broken, for those that this might help here is how I believe they solved it.
task settings -> tools -> write $hex or $HEX
